> * When Beeline prints out a {{ResultSet}} to stdout it uses the {{BeeLine.print}} method
> * This method takes the {{ResultSet}} from the completed query and uses a specified {{OutputFormat}} to print the rows (by default it uses {{TableOutputFormat}})
> * The {{print}} method also wraps the {{ResultSet}} into a {{Rows}} class (either a {{IncrementalRows}} or a {{BufferedRows}} class)
> * The {{Rows}} class will calculate the optimal width that each row in the {{ResultSet}} should be displayed with
> * However, this width is only relevant / used by {{TableOutputFormat}}
> We should modify the logic so that the width is only calculated if {{TableOutputFormat}} is used. This will save CPU cycles when printing records out to the user.
